Specification of Letters Patent.

Application filed December 20, 1912. Serial No. 737,788.

To all whom it mag concern Be it known that I, FREDERICK Bnxz, J12,

a citizen of the United States, residing at M Haledon, in the county ofPassaic and State of New Jersey, have invented certain new and usefulImprovements in Batten Structnres for Narroware Looms, of which thefollowing is a specification.

This invention consists in certain improvements in batten structures fornarrow ware looms of substantially t-bekind set forth in my applicationfor Letters Patent filed September 16th, 1912, Serial No. 718818. n theconstruction set forth in said applic tion one of the salient featuresis a peciliar disposition of the pairs of shuttle b ocks having for oneof its purposes to increase the number of weaving Spaces in the battenwithout materially reducing the width of the weaving spaces, such objectbeing accomplished partially through extend'ingthe races for theshuttles (specifically in that instance, the lower races-the battenstructure beingof the double decker type) outside of their respectiveblocks and into adjoining structure, in that case the adjoining blocksand the batten proper. It is desirable in these structures that eachblock should be capable of removal, individually, for the purpose ofrepairs, adjustment of its parts, and so on. In myprevious construction,however, this is impossible: that is to say, with each shuttle longenough properly to bridge its weaving space it must of necessity be alsoso long as to extend, when it even only just clears one of the blocks,more or less into that portion of its race which extends .beyond theother block into structure adjoining the latter: (If the blocks weremade wider it is obvious that an increase in capacity of the battenwould not lie-attained). Shuttle races must of course be provided withretaining flanges which engage corresponding flanges on the shuttles andprevent them from forward displacement. It is therefore quite obviousthat even though the shuttle in any particular block be moved in itsrace so as just'to clear the complementary shuttle blook,'removal of thefirst block would be impossible because the shut tle would beinterlocked with that part of the adjoining structure into which itprojUClS. 1

The principal object of my present invention is to avoid this and makepossible the unobstructed removal of any one shuttleblock. I

In the accompanying drawings, Figure 1 1s a front elevation ofsufiicient of the im proved batten structure to illustrate the in" is asectional view on the vention; Fig. 2 line c:v of Fig. 3; and, Fig. 3 isa plan view of two adjoining shuttle blocks.

The batten-proper a has set into the elongated rectangular recesses Z1therein, disposed 'at regular intervals, the -vshuttle blocks providedwith upper and lower sets of forwardly open grooves (Z and e in whichmove the shuttles ll and 0 under actuation from a suitable rack 7"through series of pnnons g of which each series or set is whollycontained within a shuttle block; the shuttle blocks are rcmovablysecured in any suitable manner in the. recesses b. For the purposealready indicated each race 6 extends laterally and downwardly beyondthe pair of blocks in which it is formed into adjoining structure. beingin the present instance a shuttle block-of each adjoining pair and thebatten proper. As usual, each shuttle has an upwardly projecting longi'tudinal flange h (extreme left, Fig. 1 to engage against the back of acorresponding flange i (Fig 3) so as to retain the shuttle againstforward displacement and prevent its sagging at the front.

In accordance with the present invention, I terminate the flange 2' ofeach race 6 short of the endsof said race, that is, at each point wherethe race leaves the pair of blocks in which it is formed and proceedsinto the two adjoining blocks and then into the batten proper. So far asthe two blocks areconcerned; this produces two reversed substantiallyright angular cut-outs, one in each block, or, otherwise stated, acut-out in the two blocks which is in the form'of an isosceles triangle.Thus, while sufficient of the race beyond the sides of the pair ofblocks to which it appertains is retained for the principal service ofsupporting and. guiding the shuttle, and while also sufficient of theflange is retained for preventing forward release of the shuttle, yet ifthe shuttle be shifted into one of its pair of blocks so that it more orless clears the other the first-named block can be removed, withoutobstruction, carrying the shuttle, from the batten.

In my prior construction the alternatc I weaving spaces, designated 7',projected into the grooves 0 '(shown as upwardly curved and staggeredwith relation to the downwardly curred grooves (l), interrupting thecontinuity of'the grooves'at those points andweakening the blocks. Inthe present construction, the space 7' is formed by cutting down intothe blocks appreciably short of the grooves e, and in" order that thewarp shed may have sufficient clearance the bot-- tom of-the recesswhich forms the weaving space j is inclined rearwardlv, as shown in Fig.2,. at is. Further, in each, shuttle block from the surface It down toand communieating with each groove e is cut a sight opening Z whosefunctionis to facilitate the primary adjustment of all the shuttles whenthe structure is organized.

Having thus fully described my invention, what I claim as new and desireto secure by Letters Patent is 1. A batten structure for narrow warelooms lhaving pairs of spaced removable shuttle! blocks nd forwardlyopen shuttle guiding groowseach formed in a pair of the blocks ancx1 inportions of said Struca ture adjacent 's id pair at both sides thereof,and shuttles respectively arranged in said grooves, each shuttle havinga longitudinal uprightxretaining flange and each groove having'a1similar upright retaining flange bearing against the forward side of theshuttle flange and terminating at'or within the sides of said pair ofblocks, whereby, on shifting each shuttle to a position where it clearsone block, the lattdr, carrying the shuttle, may be removed unobt dlfromxthe structure, substantially" aS described.

2. A batten sliructurev for narrow Ware looms having pairs of spacedshuttle blocks formed with downwardly curved upper shuttle-guidinggrooves d and upwardly curved lower shuttle-guiding grooves e staggeredrelatively to grooves d, the adjoining blocks in each two adjoiningpairs having formed therein a downward Weaving-spaceforming recessterminating at the front short of the grooves e and having its bottomsurface beveled rearward ljy; Substantially as described.
